Phase Singularities of Focused High-order Hermite-Gaussian Beams

摘要：

　　The phase singularities of high-order Hermite-Gaussian beams focused by an aperture lens are studied.Numerical calculation results are given to illustrate the dependence of phase singularities on the truncation parameter and beam order.The reorganization process of phase singularities of focused high-order Hermite-Gaussian beams with increasing truncation parameter is illustrated by numerical examples.
